Considering that marijuana is, by far, the most commonly abused illicit drug, we at UrineTheClear thought it was time to discuss the THC metabolite and its detectability times with regard to urine testing. Recent advancements in the field of drug testing have improved the specificity of the most frequently utilized testing method, immunoassay, more commonly referred to as EMIT.
The good news for you, the consumer, both figuratively and literally speaking, is that these enhanced testing methods have greatly reduced the number of false positives. It has also resulted in a narrowing of the “window” of detectability. That being said, the half-life of the THC metabolite can vary widely among individuals. There are currently testing methods which can detect even the passive use of marijuana in a user, though these detection times are very short-lived. Hope this info. proves helpful.
